Referring briefly to the. drawing, Figure 1 is a al View ofthe motor.

Figure 2 is a longitudinal sectional elevational View of the motor takenon line 44 of Figure 3. v I

Figure '3 is a longitudinal sectionalelevational View of the couplingunit, showing the generator and motor shafts in mutually lockedposition. Referring in detail to the drawing, the

numeral l4 indicates a funnel. The tubular member enters into acylindrical casing 16 which is completely enclosed on its sides by faceplates 17 and 18. The face plate 18has V 'a hub thereon in which one endofa'shaft 19 is'journalled, said shaft passing axially thru the casingand extending beyond the surface of the face plate 17. The shaft 19 hasa collar 20 rigidly secured thereon and a plurality of blades 21 extendtangentially from said collar. The axis of the shaft 25 of an electricgenerator is aligned with the, axis of the shaft 19 of the motor unitand the mutually adjacent, sides of the aforementioned shaftsare-provided with square ends. The square end 26 offthe shaft 19 ishoused within the-threaded sleeve-like menito' like-named V inthe-proper direction Ion 'the sleeve 271m partially sectioned elcyatioinnel 30 formed a locking block 31 which is provided with asquare opening,the latter being adapted to slip over the squareend'32 of thegeneratorshaft and the square'end I PATENT OFEICE.

26 of the motor shaft 19 and lock both shafts so that rotation in unisonof the motor shaft and generator shaft is possible. 3

The motor shaft when coupled to the shaft of the generator will causethe latter to rotate and store energy in astoragebattery; Then it is not:desired that the generator shaft 2510's rotated,lt-he "collar 28 isrotated til the block 31 is entirely seated upon the square end 32 ofthe generator shaft 25'. In

. this position it'will be noted that the motor f the generator remainsin a position "of rest.

In coupling the shafts-19:;and 25, a collar 28 isrotated in the requireddirection until the block 31 arrives at the position shown in Figure 3in which said block is supported on both shafts,.and thus locks the sameso that theyrotate in unison. I
